Definitions

  • copolyamides as hot melt adhesives has long been known (US Pat. No. 2,252,555).
  • hot melt adhesives based on laurolactam have found their way into the technique of heat sealing textiles in recent years (DE-B 12 53 449). Since these hot melt adhesives cannot fully satisfy, especially with regard to their resistance to hot water and cleaning, they have been modified many times.
  • DE-A 19 66 919 describes hot-melt adhesive based on copolyamides which contain branched-chain diamine building blocks which have improved cleaning resistance, but which have to be fixed at higher temperatures.
  • Copolyamides based on nonamethylenediamine also have too high a melting point and are therefore not suitable as a hot melt adhesive for heat sealing textiles (DE-A2508112, 2642244). Low-melting copolyamides are unsatisfactory in terms of their resistance to hot water and their resistance to cleaning (DE-A 23 24 159, 23 24 160, 24 36 430, 28 06 933). From the aforementioned US Pat. No. 2,252,555 it is also known that copolyamides in a mixture with homopolyamides are particularly suitable for bonding metal surfaces (Lc. Column 4, lines 1 to 10). DE-B 22 38 547 gives the same teaching.
  • DE-B 25 50803 teaches to use mixtures of crystalline homo- or copolyamides of laurolactam and 11-aminoundecanoic acid in certain proportions in a mixture with crystalline homo- or copolyamides of hexamethylenediamine and 1,12-dodecanedicarboxylic acid for the bonding of metals , These mixtures can also be used in the form of powders. In this case, however, it is necessary in the case of the copolyamides to use those which contain at most 5 or 10 percent by weight of other copolyamide-forming basic building blocks. It is therefore imperative to use crystalline homo- or copolyamides.
  • the melting point is defined here by melting a powder in a melting tube in a Mettler Fp 51 device.
  • the amount of the copolyamides is advantageously a) 90 to 60 percent by weight, that of the copolyamides, b) 10 to 40 percent by weight.
  • copolyamides a) should preferably contain at least 25, in particular at least 30 percent by weight of the basic building block laurolactam; conversely, this basic building block should at most be contained in amounts of preferably 60 percent by weight.
  • these basic building blocks are laurolactam or laurolactam and 11- Aminoundecanoic acid in amounts of preferably at least 30-65 percent by weight, in particular 35-60 percent by weight and at most in amounts of preferably 65 percent by weight, in particular 60 percent by weight.
  • copolyamides melt within the specified temperature limit.
  • These temperature limits for the copolyamides a) are advantageously from 110 to 140 ° C., in particular from 115 to 135 ° C. and for the copolyamides b) are advantageously from 80 to 110 ° C., in particular from 85 to 105 ° C.
  • At least terpolyamides are used in particular as copolyamides. They are obtained after the known hydrolytic polymerization. In principle, the copolyamides can also be produced by transamidation of homopolyamides. However, since this process is not economically viable, this manufacturing method is less preferred.
  • Suitable copolyamides are all copolyamides which are in the melting range specified. This also includes copolyamides that contain oligomeric or polymeric fatty acids. However, these copolyamides are less preferred.
  • the temperature range for the copolyamide mixtures according to the invention is critical. It must be in the range described above for mixed components a) and b).
  • the solution viscosity ⁇ rel (measured in 0.5% cresol solution at 28 ° C) for the copolyamides a) is between 1.4 and 1.75, preferably between 1.45 and 1.70, for the copolyamides b) between 1 , 30 and 1.60, preferably between 1.35 and 1.50.
  • copolyamides of group a) The following may be mentioned as copolyamides of group a):
  • group b) copolyamides examples include:
  • the powdery mixtures can be produced by cold grinding the granulate mixtures and then classifying them. However, it is more advantageous to mix the already ground powders, in order to avoid clumping, mixing units are used which work without shearing and heating.
  • the grain size distribution of the powders is in the range customary for the powder point process, namely 60 to 200 ⁇ m, in particular 80 to 200 ⁇ m.
  • additives can be added to the powdery mixtures, e.g. Metal soaps such as Ca stearate, Zn stearate, optical brighteners or optionally stabilizing agents such as sterically hindered phenols.
  • the powders and powder mixtures listed in the table below with a grain size distribution of 60 to 200 ⁇ m were tested. They were applied to a commercially available interlining using a powder dot machine with an 11 mash grid with a coating weight of 18 ⁇ 2 g / m 2 . On an ironing press was glued at 140 ° C with a pressure of 350 p / cm 2 with a commercially available siliconized outer material. The bonded parts were washed 3 times at 60 ° C. with a commercially available mild detergent and 5 times with a conventional chemical cleaning agent. The separation strength was determined in accordance with DIN 54 310, the values being given in N / 5 cm.
